INTRODUCTION: Adenomyosis, which affects > 20% of reproductive-age women, is a major cause of infertility. Defective decidualization of endometrial stromal cells (ESCs) is a key pathogenic feature of adenomyosis; however, the underlying red…

To investigate the risk factors influencing very early preterm and early preterm births in twin pregnancies after in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). This retrospective study analyzed 2042 twin pregnanc…

We aimed to examine abnormal oxidative lipid levels and their related mechanisms in EM-associated infertility. Through liquid chromatography tandem mass spectrometry analysis, decreased levels of epoxyeicosatrienoic acids (EETs), which have…

The extracellular matrix (ECM) constantly remodels to tailor a temporal spatial specific environment for the residing cells to respond to physiological or pathological stimuli. Endometrial mesenchymal stem cells (eMSC) are excellent therape…

Endometriosis is a chronic gynecological disease and a major global concern for women's health. With advancing knowledge of the condition, the classic definition of endometriosis as "endometrium-like tissue outside the uterus" now appears i…

Progressive dysmenorrhea and extensive fibrosis within the myometrium are hallmark features of adenomyosis (AM). Approximately 80% of patients with AM experience secondary dysmenorrhea, which occurs more frequently in AM than in other gynec…

OBJECTIVE: To assess the ovarian reserve and in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes after various laparoscopic approaches in infertile patients with endometriomas and suspected compromised ovarian reserv…

Through a combination of single-cell/single-nucleus RNA-Seq (sc/snRNA-Seq) data analysis, immunohistochemistry, and primary macrophage studies, we have identified pathogenic macrophages characterized by Tet methylcytosine dioxygenase 3 (TET…

STUDY QUESTION: What molecular mechanisms underlie the decline in ovarian reserve as the number and quality of oocytes decrease in patients with ovarian endometriomas (OEM)? SUMMARY ANSWER: Elevated expression of the let-7 micro(mi)RNAs in…

To investigate the effects of pretreatment with long-acting gonadotropin-releasing hormone agonist (GnRH-a) before frozen-thawed embryo transfer (FET) on pregnancy outcomes in patients after minimal-mild (stages I-II) peritoneal endometrios…

Abstract Study question What is the expression profile of lipid peroxides in endometriosis (EM) follicle? What is the function of differentially expressed lipid peroxides in endometriosis-associated infertility? Summary answer 14,15-EET con…

Defective decidualization of endometrial stromal cells (ESCs) in endometriosis (EM) patients leads to inadequate endometrial receptivity and EM-associated infertility. Hypoxia is an inevitable pathological process of EM and participates in …

Abstract Severe endometrium damage causes pathological conditions such as thin endometrium and intrauterine adhesion, resulting in uterine factor infertility. Mesenchymal stem cell (MSC) therapy is a promising strategy in endometrial repair…

Endometriosis is a common gynecological disorder that causes female infertility. Our recent research found that excessive oxidative stress in ovaries of endometriosis patients induced senescence of cumulus granulosa cells. Here, we analyzed…

Rudimentary horn of the uterus is a rare congenital malformation that is characterized by significant anatomic variability. We report two cases involving women who presented with a broadly attached rudimentary horn and large ovarian endomet…

The mechanism by which endometriosis, a common gynecological disease characterized by chronic pelvic pain and infertility, causes infertility remains elusive. Luteinized unruptured follicle syndrome, the most common type of ovulatory dysfun…

This study aimed to compare ovarian reserve function and outcomes after in vitro fertilization and embryo transfer (IVF-ET) for young women with pelvic endometriosis with or without ovarian endometrioma. We explored the main factors influen…

The outcomes of in vitro fertilization (IVF) for endometriotic women are significantly worse than for patients without ovarian endometriosis (OEM), as shown by fewer retrieved oocytes. However, the exact pathophysiological mechanism is stil…

The pathological expression and function of lactate dehydrogenase A (LDHA), a key enzyme that converts pyruvate into lactic acid during glycolysis, remains unknown in endometriosis. In the present study, LDHA expression in tissue samples wa…

ABSTRACT: This study investigates the effect of 2 laparoscopic methods on ovarian reserve in patients of reproductive age with endometriomas.This was a retrospective study performed at a tertiary medical center from Jan 1st to Dec 31st, 201…

Endometriosis an important cause of female infertility and seriously impact physical and psychological health of patients. Endometriosis is now considered to be a public health problem that deserves in-depth investigation, especially the et…

ABSTRACT: The NOD-like receptor protein 3 (NLRP3) inflammasome is a key regulator of the host's immune response, and many immune and metabolic disorders are linked to its activation. This review aimed to investigate and clarify the relation…
